Castlepark House has a central pedimented two storey breakfront, made all the more distinctive by the Venetian window on the first floor which has a small lunette window, almost like a halo, above it.

At S. Vitale, above the lunettes, flying angels hold up clipei, and it is angels in this position that are also found on the marble table altar made by Bernard Gelduinus, in Toulouse, probably about 1096.

Still in their original oak frames, the importance of these lunettes lies not only in their intrinsic appeal, but also in their importance to a major interior in Beckford's last architectural project.

Gaspare Celio, writing in 1638, divides the work, stating that the altarpiece is by Giulio Romano and that all the paintings above the cornice (that is, in the lunettes and in the vault) are by Penni.

Giani wrote in his Preface that the Servite lunette paintings should serve as an example for narrative painting in general, and focused on their didactic function and their role as a visual stimulus to piety.

In the late cinquecento, Florentine patrons seized upon the cloister lunette fresco cycle as an ideal format for reformist didactic painting.
